Generating complex but smooth polysurfaces

Rhino Rhino for Windows

I am making a polysurface and I am having trouble making smooth transitional surfaces to make the poly surfaces seamless. I am using the Sweep2Rails and Surface from Curve Network but I am still seeing hard breaks. Any advice. I can send screenshoot and even upload my model. Thanks

Why not just do that in the first place?
